The upper ends of the outer walls ofthe reen orcing members12'and13curvelintfardly as at 19 and 20, to form relatively Aflat upper ends, for apurpose te be '-l'i'er'ciraffter described. The lower ends ot reenforcing members 12 and 13 cur've inwardly,"as at21 and 22, 'and thence outwardly, and 24,1so that when the reenorcing mem bersare driven iinto thegr'ound alongside the ypole the lower ends tend to move towards an'dti'ghtly embrace the butt Y of the pole. 4 y n p y `Arranged atsuitable intervals throughout the length of the reenforcing members-'are inwardly -facing pockets 2,5, 26,27 and 28 into which preferably flexible metallic straps"2930, l31 and 32.pass-rom the-exteriorl of the reenforcingfmember, walls '14 and 1 5 being provided with "openings 33 and 34, the side wallsotpockets 25, 26, 27 and 28 being provided with openings 35 through which the strapsL pass, At the bottom of each of .the pocketsl 25, 26,27 and 28 are lugs 36'rhaving sockets n37 in which the lower lends of dogs 38 are received, dog's 38 having their inner jfaces bearing against "str-aps 29, 30, `31 `and j 32 and being provided onf'their opposite @sides with a plurality of notches or indentati'ons 39 in which key members v'40 -may be received to hold the dogs tightly in place. pening to the l*exterior `.of reenforcing members 12 and 13 through walls 16 and into the pockets 25, 26, 27 and 28 are substantially T-shaped openings 41, '42, v43:l and 44, the upper ends of these openings providing for the ready introduction `of keys. -40,-and the lower' of these openings providing vfor the introduction offa'pinclnbar or crowbar, the lower end of which may be brought to bear 'againstthe inner surface of wall 16, as at 45, .and against ythe dogs v38,at A43, to force the latter inwardly against the straps 29,30, `31'and 32. It desired, the reenforcing members may be reentorcedby one or more longitudinally direct-ed webs 47 and transverse webs 48.

One; or more reenforcing members i12 .or 13 may be driven into thehground alongside a pole in a position ywhere 'they-bear tightly against the pole. When used in this manner, the reenitorc-ing members 12 and 13 provide a convenient'means-for driving, while the relatively thini inwardly curved lowerportion yof the members tends to forcev the members towards the/pole, or

"and "32 are"threadedthrough the openings 33, 34 and 35.

Dogs 38`are inserted through openings 41, 42, 43 and 44, the lower ends of the dogs resting li`n't`h`e sockets 37, while the inner 'li-aoesthereot bear against straps 29, 30, 31 and Key members 40, which inlthis vins-tanceareot rod-like form, 'arenow introducedthrough the upper ends of 'T-shaped openings 41, 42, 43 and-44, whereupon ra crow-bar or pinch bar is introduced successively in vopenings 41, v42,7743 Zand .44 -fand brought to bear against thelinner surface of wail V16 at 45,-and `then againstthe'dogs 38 at 4G'to force the latterinwardly` against th'e straps-29, 30, 31 and32. Asthe straps 29, 30, 31 and 32 are drawn through openings and 34 by the 4action et' the' ydogs 38thereon, theylbind against the reeniioreing members 12 and 13 and or'c'ethem against the surfacevot the pole 10 which they tightly embrace. `Upon inward movementof dogs 38,key members 40 arereceived successively'in thenotches 39 .and bear against the inner surface olf wall l-ltovholdlthe dogs againstoutward movement .away from the straps. Y

In Figs-7- and 8l have shown ay modification in which the' rod-likekeys 4Q are-replaced kby balls f49-introd'uced through -openings 50in walls 53, balls 49 being-adapted tojbe received in sockets 51 in vdogs 52 fand to bear against'the inner surfaces yot walls 53,7.the latter bein-g unbroken fromiopening 50 to the openingf54, which not only serves for the introduction lotthefdogs 52 intothe reenioreing member but permits the introduction of the end ot a pinch harto torce the dogs against the straps. I

Fromthe above descriptionr of my invention, it will be readily seen that I have-provided a reenforcing member for a telegraph pole or the like presenting af substantially smooth outer surface `with no lprojecting parts, and whichfmay be readily and yquickly-clamped against thefside offa telegraph pole or the like, the clamping means being locked securelyin-place. n

While I'have Ashown and described,l a preferred' embo'diment oi"Y my. invention, it will be understood that it -is Y not -*to be I limited to all the details shown, butwis capable yof modification and variation within the spirit ofthe'inventionand the scope 'ofthe-appended claims.
